SPECIFICATION forming part of Letters Patent No. 548,47' 1, dated October 22, 1895.

Application led J'muay 31: 1895 .To if/ZZ whom it may concern:

Beit known that we, AUGUSTUS J. SMITH, a resident of Hammonton, New Jersey, and JOHN W. SINNIcKsoN, a resident of Philadel- 5 phia, Pennsylvania, citizens of the United States, have invented certain Improvements in Bottle-Stoppers, of which the following is a specication.

The object of our invention is to construct to a device which is at once simple in construction, economical in cost, and efficient in operation for preventing the reintroduction into a bottle supplied therewith of any liquid after the original contents of the bottle have 1:5 been either wholly or partially discharged.

This object we attain in the manner hereinafter set forth, reference being had t the accompanying drawings, in which- Figure 1 is a sectional view of a bottle prozo vided with astopper designed in accordance with our invention to prevent the refilling of the bottle, the parts being shown in the position which they assume when the contents of the bottle are being poured out. Fig. 2 is a z view, partly in side elevation and partly in section, showing the position assumed by the parts when any attempt is made to refill the bottle by submerging the same. Fig. 3 is a transverse section on the line 3 3, Fig. 2. 3o Fig. 4s is a sectional view of a skeleton valveretainer intended as a substitute for the perforated retainer, shown in Figs. l and 2. Fig. 5 is an end view of said skeleton valveretainer. Fig. G is a section al View of another and preferable form ot skeleton valve-re iainer, with which is combined a deiiector or guard for preventing access to the valve; and Fig. 7 is a sectional view illustrating still another feature of our invention.

In Figs. i and 2, A represents part of the body, and A the neck, of a bottle, these parts being constructed in an ordinary manner. Secured within the neck of the bottle in any suitable wayis a valve structure coinprising a valve a, a valve seat b, and a valveretainer d, these parts being so constructed that the valve can haveacertain amount of play between the valve-seat and retainer,

said valve having a conical back and the retaner having a corresponding conical recess. 5 o

The valve-retainer d has openings f for the passage of the liquid contents of the bottle, and it has also, by preference, a central opening g to permit ol' the passage of air or liquid behind the valve and prevent it from sticking in the conical recess in the retainer.

When the bottle is tipped so as to pourout its contents-as shown, for instance, in Fig. 1- the valve drops into the recessin the retainer and permits the outtlow of liquid through the 6o opening in the valve-seat and those in the retainer; but when the angle of inclination of the bottle is lessened, as shown in Fig. 2, the valve ci closes against the seat b, this action, owing to the conical form 0f the back of 65 the valve and of the recess in the retainer, taking place some time before the bottle has reached the horizontal position. Hence the valve is firmly closed against its seat by gravity before there is any possibility of elfecting 7o any entrance of liquid into the bottle by submerging the same, for in order to elfect this result the bottle would have to be held in a substantially horizontal position, and, as shown in Fig. 2, the valve a is closed against its seat while the bottle is still inclined sharply upward.

As shown in the drawings, the valve structure is constructed for being secured in the neck of the bottle by means ot' some suitable 8o cement; but if desired the bottle may have an internal shoulder, as shown by dotted lines in Fig. l, for supporting the valveseat, and the valve structure may be held in place against said shoulder by any suitable form of retaining device above the same.

The valve structure will in most cases be used in combination with some form of protector located above the valve-retainer d and constructed to prevent access to the valve, so 9o as to hold the same open. As an instance of one form of protector which may be used we have shown in the drawings by dotted lines a pair of perforated plates one above the other, the perforation of one plate being op- 9 5 posite an imperforate portion of the other Y but being opened as soon as the valve moves away from its seat, so that the air can pass through the tube to the space above'the liqplate, so that access to the valve by means of an inserted wire or other implement is effectually prevented.

Instead of forming the valve-retainer with perforations f, as shown, the said yretainer may, if desired, be in the form of a slotted or open-Work cage-such as shown, for instance, at C in Figs. l and 5 or at cl2 in Fig. G--and in this case the opening g at the top of the retainer will probably not be necessary.

In connection With the open-Work or skeleton retainer shown in Fig. 6 We have also shown a protector consisting of a disk i above the retainer, this disk preventing access to the valve-from the opening iin the top of the casing m of the valve structure.

In order to provide for a free How of liquid from the bottle, it is necessary to'convey air to the space above the liquid in the inverted bottle Without forcing it to find its' way through said liquid, and for this reason we combine with the valve-seat b a tube n, leading therefrom to a point close tothe bottom of thebottle, the month of this tube being closed by the valve a. when the latter is seated,

uid in the bottle, thus insuring a steady and uninterrupted flow.

In Fig. 7 we have illustrated in connection with the valve ci a sliding stop-block s, adapted to a curved channel in the back ot' the retainer d. Whenever the bottle is held in an upright position, this stop-block seeks the lowest point in the curved channel and holds the valve a firmly against its seat; but when the bottle is tilted in any direction the stopblock drops to one side of the curved channel and frees the valve a.

As will be understood from the different methods of construction which We have illustrated in the drawings, the details of the valve structure may` be widely varied Without departing from the essential features of our invention so long as the valve has a conical back and the recess for the valve in the retainer is likewise conical and is so disposed in respect to the valve-seat as to direct the valve onto the same when the bottle is held at an angle approaching the horizontal, the valve having no lateral support except that afforded by the Walls of the conical recess of the retainer.

Having thus described our invention, we claim and desire to secure by Letters Patentl. A bottle stopper comprising a valve seat, a valve with conical back, and a valve retainer With conical recess for receiving said valve and for directing the same against the valve seat when the bottle is held in a position approaching horizontal, substantially as specitied.

2. A bottle stopper comprising a valve seat, a valve having a conical back, anda valve retainer with conical recess for receiving said valve, and directing the same against the valve seat when the bottle is held in a position approaching the horizontal, said valve retainer having openings for the passage of liquid therethrough, substantially `as specifled.

f 3. A bottle stopper consisting of a valve seat, a valve having aconical back, a valve retainer .having a conical seat for the reception of said valve, and openings for the passage of liquid therethrough, and a deilecting plate for preventing access tothe valve through said openings, substantially as specified.

4. A bottle stopper comprising a valve seat, a valve having a conical back, a valve retainer having a conical seater recess forthe reception of said valve, passages in said seat for the flow of liquid therethrough, a casing having an opening in the top, and a deflector plate mounted above the valve retainer and below the opening in the top of the casing, and serving to prevent access to the valve through said opening, substantially as speciiied.

5. A bottle stopper comprising a valve seat, a valve adapted thereto and a retainer for limiting the outward movement of the valve, in combination with an air tube extending from the valve seat down into the bottle and adapted to be closed when the valve is on its seat, and opened as the valve leaves its seat, substantially as specilied.

6. A bottle stopper comprising a valve seat, a valve adapted thereto and having a conical back, a valve retainer having a conical recess, and a laterally movable stop block, which when the bottle is held in an upright position, prevents rise of the valve from its seat, substantially as specified.

In testimony whereof We have signed our names to this specification in the presence of two subscribing Witnesses.
